30 wrz 2020 · Chemicals with pH values from 0 up to 7 are acids, those with a pH value of 7 are neutral, and those with pH values greater than 7 up to 14 are bases. Here is a table of pH values of common chemicals. You’ll see charts that give slightly different pH values for some chemicals. There’s usually a pH range for a substance.
pH is a measure of how acidic or basic a substance is. It takes a numerical value between 0 and 14 that measures the relative amount of free hydrogen and hydroxyl ions in water. Water having more hydrogen ion concentration than hydroxyl is acidic.

With this pH calculator, you can determine the pH of a solution in a few ways. It can convert pH to H+, as well as calculate pH from the ionization constant and concentration. The pH value is an essential factor in chemistry, medicine, and daily life. Read the text below to find out what is the pH scale and the pH formula.
Alfa Chemistry provides the following pH table of common acids and bases for your review. We hope to help you make it easier to determine the pH of an acid or base (valid for standard conditions at 25 ℃, 1 atm). The pH scale ranges from 0 to 14, with 7 being neutral.
Explore the pH of different substances and learn about acids, bases, and neutral compounds with this interactive simulation.
The pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold. For example, a pH of 3 is ten times more acidic than a pH of 4. Likewise, a pH of 3 is one hundred times more acidic than a pH of 5. Similarly a pH of 11 is ten times more basic than a pH of 10.
